[A new reconstructive technique in cases of mitral insufficiency caused by the elongation of the chordae tendineae of the anterior cusp. A case report].
A new technique is proposed for mitral incompetence due to elongated chordae tendineae of the anterior leaflet. It consists in shortening the chordae tendineae of the leaflet level. First, we make a longitudinal orifice in the anterior leaflet just near its free edge and the elongated chordae tendineae. Through the orifice and with the help of a micro nerve hook we pull the elongated chordae the necessary to keep the anterior leaflet in the same level of the posterior leaflet. The orifice is then closed with a polipropilene 5-0 suture. The mitral annuloplasty was performed with a Gregori IMC prosthetic ring. The excellent clinical and laboratorial data suggest that mitral insufficiency due to elongated chordae tendineae can be corrected by this technique.
